Ray - could I trouble you to give me a brief description of the two? (Green and Beaclh Wash). I haven't kept up with them, yet your vote of confidence carries a lot of weight in my book.
Greenwash augments the cleaning effectiveness of SH.
1. Breaks the surface tension on the cleaning surface.
2. Allows deeper penetration of SH solution into stains.
3. Allows SH reaction to happen at a lower overall SH concentration.
4 Allows SH reaction to happen at lower (winter) temperatures.
5. Allows SH to dwell longer on horizontal surfaces.
6. Includes rinsing agents that fight hard water spotting.
7. Includes a masking / cover scent.

I think he meant PM for Bleach instead of Bleach Wash.
PM for Bleach is a buffering soap that can be used to reduce the damaging effects of caustic cleaners. It also can be used as a final rinse on siding, windows, wood fences, and decks. It helps redce hard water spotting on windows and even adds shine to weathered vinyl siding.

Thank you Marcus.

Guys I used 1/3 SH what I normally use on first roof. Same touchups. No moss. So the only diff was how much SH I used.

The way we used to washing roofs, add some surficant to thicken it up. My thoughts and reading thread too.

I'll try a 4% next time when I see moss. The cider knocked it out!!!!

Also a 4% solution knocking on the doors of cider. Total SH.

Ted...
Marcus nailed it, the PM bleach wash seems to " kill" the chlorine on windows. It cuts my rinse time in less than half whe rinsing windows with dried house wash or roof mix on them. I apply with a hose end sprayer and then use my pump and water for final rinse. Have also been applying it to the gas station canopies I've been cleaning this past week. I've found that it helps with diesel soot too that the SH mixture leaves behind.

Good feedback Ray. Thanks. I never know i would remove diesel soot. What ratio are you using it at?

Not sure of the ratio, as I'm putting it in a hose end "miracle grow" type sprayer and applying it that way. In all fairness I've not tried it on a super heavy stained canopy such as a truck stop, but it did take off some soot stains on canopies that remained after I soft washed them.
